ARNOLD W. ZIMMERMAN, OF INDIANAPOLIS, INDIANA'.

REFRIGERATOR.

SPECIFICATION formingpart of Letters Patent No. 250,322, dated November 29, 1881,

Application filed April 15, 1881. (No model.)

To all whom it may concern:

Be it known that I, ARNOLD W. ZIMMER- MAN, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

The object of my said invention is to produce an inexpensive refrigerator, but one which at the same time shall be of superior construction and convenience, for the use of families, butchers, grocers, Suc. and it consists 'of the construction and arrangement of parts, as hereinafter particularly described.

Referring to the accompanying drawings, which are made a part hereof, Figure l is a perspective view of my improved refrigerator, the door and cover being open; Fig. 2, a central vertical section thereof on the dotted line w .r in Fig. 3; Fig. 3, a top or plan view of the refrigerator, the top or cover being removed and Fi g. 4, ahorizontal section,lookin g downwardly from the dotted line y yin Fig. 2.

In said drawings, the portions marked A represent the surrounding wall of the refrigerator; B, the door therein; C, the top or cover thereto; D, the shelves therein, which are mounted on rollers d d; E, the ice-receptacle, and F the drip-pipe.

The Wall A is constructed of an inner sheathing, a', a paper lining thereto, interposing hoops a2, and an outside wooden sheathing, a3, also having a paper lining. The hoops a2 are preferably constructed of two parts, and a third paper wall or lining interposed between the parts. This construction is light and very strong, and gives two deadair spaces, s s, which entirely surround the vertical portion of the refrigerator, and, as paper is one of the best of non-conductors, makes this refrigerator very superior in this particular. The portions representing the paper are designated by the letter lo.

rI he shelves are loosely mounted on rollers d d, whichare -attached to the inside of the wall A. By this means s`aid shelves are enabled to be easilyrotated. The articles mounted thereon are thus made easily accessible to the person handling the same without said person having to reach far inside the refrigerator, or, in case of a large one, to step inside it.

The ice-receptacle is similar in form to the refrigerator, but is of less diameter. It is suspended to the sides thereof by the hangers c c. It is constructed preferably of galvanized iron, and its bottom is inclined or sloping, with several orifices at the lowest point thereof.

A space is left entirely around the sides of the ice-receptacle, between it and the walls of the refrigerator, being interrupted only by the hangers e e. A space being also left between it and the cover, the air has a perfectly free circulation entirely around the ice-receptacle and into all parts of the refrigerator.

The bottoln of the ice-receptacle, being of metal, is well adapted to condense the moisture in the refrigerator, and, being inclined, will carry the same to one side, where it will fall into the open mouth F of the pipe F and be carried away out of the refrigerator, thus keeping it much drier than where the water formed by condensation is allowed to collect and remain in the same.

Underneath the lowest side of the icereceptacle is the drip-pipe F, having an open and preferably Haring mouth, F', located directly below the oriiices in the receptacle, and adapted to receive and carry olf the water formed by the melting of the ice or otherwise. As the mouth of the drip-pipe is of sufficient size to cover all that portion of the ice-receptacle from which water will fall, and is not connected to said receptacle,it is adapted to catch the water which forms by condensation on the outside of said receptacle, as well as that which comes from the inside thereof.

In small refrigerators I use an ice-receptacle of semicircular instead of circular form, which leaves one-halfthe area of the refrigerator unobstructed at the top 5 and, instead of using the door B, I construct the cover C in halves and hinge them together in the center, so that the raising of one half of said cover will give access to the interior of the refrigerator. This construction is considerably cheaper than the other, but serves the purpose equally well in the small sizes.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A circular refrigerator the walls of which are composed of an inner and outer set of pa- IOO per-lined staves, a double set ot' hoops, and a paper partition between the hoops, substantially as shown and described, and for the purpose specified.

5 2. In a refrigerator, the combination of the continuous sheet-metal ice-receptacle E, of a little less diameter than the inside of the refrigerator, and suspended thereto by hangers e e, and having a sloping bottom with several 1o small orifices therein, which will pass the Water but retain solid matter, and the drip-pipe F, having enlarged mouth F', which comes near but not in Contact with the bottom, when all constructed, arranged, and operating substantially as shown and described.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this lith day of April, A. D. 1881.

ARNOLD W. ZIMMERMAN.
